is rotated, but which are held out of engagement with the ratchet-wheelsby a pin 09 when the pistons 92 are down. These ratchet-wheels are keyedor otherwise rigidly ailiXed to the engine shaft 413. \Vhen the fluidpressure is admitted to the bottom of one oi the cylinders 01, it willpush its toothed rack upward, and, through the mechanisn'i abovedescribed, it will. rotate the engine shaft in one direction. hen theother rack is pushed upward, the engine will be driven in the oppositedirection.

100 is an electrodynainic machine which is connected to run with theengine 20 by means of a SPTLOCl-IGlL-Cllttlh 101 running oversprocket-wheels on both. the engine and armature shafts. 102 designatesthe leads from the armature oi. the electrodynamic machine, and 103 theleads from its iield windings. These will thence run to various contactsof a reversing switch 104. which comprises two actuating magnets 105 and100, together with other connected parts. One of these magnets and itsconnected parts are shown somewhat in detail in Fig. 19.

in Fig. 17 l have shown an electrically controlled governing device 110which coinprises an arm 111 pivoted at 112 and arranged to be held incentral position by a pair of weightei'l arms 113. connecting rod whichis connected to the throttle valve lever 33 and with the sparkshiitinp;lever 57, is pivotally attached to the man 111 at 11-1.

130 is a manually operated car switch which comprises a pivoted lever131 carrying a movable contact 132 which is arranged to be moved ontothe stationary contacts mounted upon an insulated base 133, whichcontacts I will point out in tracing the various circuits,and indescribing the operation of the apparatus.

14-0 is an elevator hoisting apparatus mounted upon the base 10. Itcomprises a trame 141 which forms bearings for a shaft stationary I Thevertical l l l is noon which are rigidly mounted a gear 143 and awinding or hoisting drum It worm-gear 141-5 on the shaft 81 is in 143and is so arranged one direcdruin 1 14i- 11 1. mesh with the gear thatwhen the engine 20 is run in tion or the 0tl131,1t will cause the to berotated thereby.

116 designates an elevatorar which is connected with one "do of the drum1% by ropes or cables 1 =un over suitable supporting and guidingsheaves.

1&8 is a counterweight connected with the other side of the drum 1-14:by ropes or cables 149.

150 is a storage battery, the two ends or which are designated by andThis battery is connected with the various parts of the apparatus bycircuits which will now be traced.

151 is a conductor leading from one end of the battery to the contactplate 132 of the car switch. When an operator in the car turns the leverof this controlling switch in either direction, this contact will bemoved onto stationary contact 134; which, through conductor 127, willclose a circuit through the winding; of magnet 121, back to the batteryby conductor 152. The valve 122 will then admit pressure tr in thepressure tank 67 to the cylinder 87 which will release the brake. It theoperator turns the lever to the left, another circuit will be completedthrough contact 185 and conductor 12S, through winding of magnet 121%,and through conductor 129, to contact 17 of switch 16; through. the 1switch and, out by contact 18 and conductors 153 and 152, to thebattery. This will cause the pressure tank to be connected through pipes'16 and 79 to one of the cylinders 91 of the starting device which willthereby be actuated. and will rotate the engine shaft in one direction.This rotation of the engine shaft will cause the engine to draw in anexplosive mixture which will be ignited by the spark mechanism which isconnected through the rovers ing switch, and through a spark coil 10?,with the battery. The engine will then run under its own power and willdrive the centrifugal governor 410 which, through the connectionspreviously described, will open the switch d6, thereby cutting off taeelectrical supply from magnet 126. The valve 125 will then be closed sothat the fluid pres sure starting device will no longer be sup pliedwith fluid pressure, and its piston will be driven back by the spring 93to its initial position. At the same time, a circuit will have beenclosed between contacts 132 and 135 of the car switch, conductor 12%through magnet 106 of the reversing switch, and back to the battery byconductor 15 1. This will cause 'he magnet 106 to be energized and toclose the right-hand portion of the reversing switch 101, therebyconnecting the armature leads of the electrodynamic machine and theleads from the field winding ot the latter tery in such a direction asto cause it to rotate in the same direction as the rotation of theengine 20. The electrodynamic machine will then act as a motor and willdrive the engine together with the movement which has been impartedthereto by the fluid pressure starting device 90. As soon, however, asthe engine attains its normal speed, the

a riaratus with the batl r l I l elect-rodynamic machine will be driventhereby at a sutlicient rate of speed to cause it to generate currentback into battery 150 to thereby keep the battery charged. It may beseen from the circuits shown that the sparking devices on the enginecylinders will be connected through the reversing switch contacts,through the spark coil with the battery. A further movement of thecontrolling switch lever will cause the contact 132 to be moved onto thestationary contact 136. This, through conductor 116*, will close acircuit through one of the magnets 116 which is connected by thereturnwire 155 with the battery. This magnet 116 will move the pivotedlever 111 and the connecting rod 31. to advance the spark mechanismactuating cams to cause the engine to run faster. It will at the sametime open the throttle valve to further in crease the speed of theengine. Similarly, contact 132 of the controlling ear switch may bemoved onto stationary contact 137 which will then close a circuitthrough conductor 11G through the second magnet 116, to move the pivotedarm 111 a further amount to further increase the speed of the engine.When the controlling switch is moved to its extreme position to theleft, a circuit will be closed through the contacts 132 and 138, throughconductor 116 to close a circuit through the third magnet 116. which,through the mechanical connections above pointed out, will furtheradvance the spark mechanism and will fully open throttle valve 30. Theengine will now attain its full speed which will be controlled by thecentrifugal governor 10. This is so arranged that whenever the engineattains undue speed it will close the throttle valve to prevent racingof the engine. The controlling switch 130 is placed in the elevator-car146. The rotation of the engine obtained in the manner above describedwill cause the car to be driven up or down, as the case may be. Thus, anoperator in the car may start up the engine to start the car in onedirection and cause this movementto be accelerated at will. The operatormay at any time move the lever of the controlling switch back off ofcontacts 188, 137, or 136 to deenergize any of the magnets 116, and maythus reduce the speed of the engine and of the car by shifting thesparking mechal l l l nism and closing the throttle Valve 30, or he maystop the engine and bring the car to rest by moving the car-swrtch leverback to its central position, when the valve 120 will be closed, theignition current cut off, and the brake applied. It the operator desiresto start the engine and the car in the opposite direction, he may turnthe carswitch lever 131 to the right, when operations similar to thoseabove specifically described will take place, but in this case theelectrodynamic machines leads will be connected to the battery in such adirection as to cause it to rotate in the opposite di 'ection, and theother cylinder 91 of the fluid pressure starting device will be suppliedwith fluid pres sure through the valve 123 and pipe T8, so that thesetvo mechanisms will drive the engine, and consequently the car, in theopposite direction. The speed at which the car is run then may becontrolled through the magnets 115 of the electrically controlledgoverning mechanism 110, which magnets are controlled by suitablecontacts in the controlling switch.

Dy means of the apparatus above described, a simple and positive controlfor an elevator driven by an internal combustion engine is provided. Theengine itself is directly connected with the elevator apparatus and boththe fluid pressure supply and electrical energy which are used forstopping and starting the engine, and the apparatus and the engine whichit drives are generated by the engine itself. This invention, theretore, opens up a new held for the use of internal combustion engineswhich have not hitherto been applied to drive elevators, except "hroughintermediate mcchanisi'ns,such, for example, as a continuously drivenshaft connected with the elevator hoisting mechanism through clutches.This is partly because engines of this type have been dillicnlt to startand control. Butthe simple arrangementwhich I have herein disclosedovercomes these ditiiculties and provides a means for starting theengine in either direction, and a suitable means for controlling itsspeed and bringing it to rest at will. liloreover, all of theseoperations may be controlled by a simple manually operated switch in thecar.

The power generating device is complete in itself and is directlyconnected with a hoisting apparatus. In other words, the motive power isthe engine which produces its own power and does not merely transformone term of energy into another as is the case where steam engines orelectric motors are used.
